20% Pully

[ufo8mycow]

What is this 20% under drive pully, any real benifit for a stock standard VZ Berlina?

[GEN3RATD]

they work by slowing down the speed that the accessories spin at (by 20%) therefore less power drain, less strain on the engine, more power.
thats about the limit of my knowledge lol.
